Antiplatelet medication is very important in the treatment of thrombotic disorders. Antiplatelet drugs include: 1. Aspirin, which is mainly used for the prevention of thrombotic disorders and maintenance therapy after heparin application. The common dose range is 75-300 mg per day, and the specific dose should be chosen according to different conditions. 2. dipyridamole, which can inhibit platelet aggregation, is usually administered intravenously at 500 mg per day. 3. clopidogrel, whose trade name is Bolivar, is a specific platelet aggregation inhibitor, and is often used clinically for the treatment of acute myocardial infarction, and is generally well tolerated. 4. ticlopidine, which has a mechanism of action similar to that of clopidogrel and is commonly used at a dose of 150-250 mg per day, has been replaced by clopidogrel due to the high incidence of hematologic adverse reactions.
